I want to glue PVC insulated 1mm dia wire to a bare piece of wood.
It should secure the wire to the wood but really the only force it needs to resist is gravity.
It shoud be removeable cleanly from the wood if necessary.

Which glue do you think will best meet these requirements?

 

Doing similar I have used Devcon 5 minute epoxy. You mix two parts and it sets up in about 5 min. It peels off wood depending on the surface finish of the wood. You might also consider plain old Elmer's Wood Glue depending on what's available where you are.

My goto is E6000, previously known as Goop from EclecticProducts.com .


There may be different versions. I get the version with all the bad stuff in it.* It goes on viscous, skims over quickly (i.e., is difficult to work), but sets by evaporation to a very thin and highly tenacious rubber. In my experience, it is safe on PVC, acrylic, and most other plastics.

Second choice is a low-temp hot melt. Epoxy also works, but is rigid.

*Perchlorethylene

I go out of my way looking for a skull and cross bones on the package.

If you want it to be easily removable try using Electrical putty, called Duct Seal it bonds to just about everything but can also be removed if needed.
Home Depot etc carries it.

It's not exactly what you asked for, but you might consider a Command Clip. They aren't cheap but they work very well and are specifically designed to be removable.

 

My inclination would be to use hot melt glue. No nasty chemicals and no mixing needed.

The temperature for hot melt glue is, I think, at least 120°C. Is that safe for PVC insulation?

 

I thought the original intention was to fix a 1mm conductor just temporarily?
If using a hard setting adhesive, surely it is likely to damage the conductor on removal.?

The wires (4) are to be attached permanently if the experiment works. If I need to rethink I want to be able to remove the wires without damaging the wood. It doesn'r matter if the wires are wrecked by removal.

Nice idea but they are too big. The wood is just 9mm wide.

I can't find that over here.

 

highly tenacious rubber

Sounds like it might be difficult to remove?

 

Devcon 5 minute epoxy

That sounds like a plan and it's available over here. I feel a test coming on...

My bad. Checking the Web indicates the hot melt glue would be too hot. All of the temperatures were for continuous exposure to the high temperature.

However, I have done it without any obvious problems. I suspect that the glue cools quickly because of the copper wire inside the PVC insulation. Keep in mind that you can solder PVC insulated wire -- if you are careful.

A test would be needed to know if the hot melt glue works safely with your wire.

I do have a gun and glue to try this so I will give this a go. The wire hasn't arrived yet though...

There are only three kinds of insulation Kynar, Teflon and PVC. You can probably do the test on just about any wire you happen to have around.

I would definitely test in advance.

Not at all. Slice along the joint between the wood and wire. Separate the wire from the wood. Then peel the adhesive from the wood. Adding a little chlorinated hydrocarbon solvent (e.g., methylene chloride, chloroform, PERC) will help make the rubber stretchy so it removes just like the 3M removable stickies do.

I made a base loaded antenna on a balsa wood form and had to redo it recently. Removing the wire was simple following that procedure. I did not try to remove the glue from the wire.

Adhesives present interesting challenges to chemists. Some people want permanent adhesives; others want strong adhesives that are removable, and so forth. I would call Goop a strong, flexible, and generally permanent adhesive that can be removed if needed. Of course, you could use Post-It tape, if you really want it to be easily removed.
